The messaging-friendly LG Optimus Pro C660 that appeared yesterday in Italy has been officially announced today, alongside another new member of the Optimus family: the LG Optimus Net P690.

Both smartphones run Android 2.3.3 Gingerbread, and are sub €200 devices that should build on the success of the Optimus One P500.

As reported yesterday, the Optimus Pro features a full QWERTY keyboard, and a 2.8 inch QVGA touchscreen display. Luckily, it also has HSDPA, Wi-Fi 802.11 b/g/n, GPS, 3.5mm headset jack, 3MP camera, 256MB of RAM, and an 800MHz processor.

Here’s an official video preview of the Optimus Pro (in Italian):

The LG Optimus Net P690 seems to be the rightful successor to the Optimus One. However, apart from a more powerful processor (800MHz instead of 600MHz), Bluetooth 3.0, and the newer version of Android, it doesn’t have too many enhanced features: it’s still a 3.2 inch HVGA phone. Sure enough, the design has been improved. Here’s a video preview of the P690, also in Italian:

According to LG Italy, the Optimus Pro will cost €179, while the Optimus Net should cost €199. Both smartphones will be likely available pretty soon across Europe.
